CVE-2026-25957
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedCube is a semantic layer for building data applications. From 1.1.17 to before 1.5.13 and 1.4.2, it is possible to make the entire Cube API unavailable by submitting a specially crafted request to a Cube API endpoint. This vulnerability is fixed in 1.5.13 and 1.4.2.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA specially crafted request to a Cube API endpoint can cause the entire Cube API to become unavailable, resulting in a denial of service. This affects versions 1.1.17 through 1.5.12 and 1.4.1.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed Cube.js versionRun 'npm list @cubejs-backend/server' or check package.json for @cubejs-backend/server version. If using Docker, check the image tag or digest.Affected if The version displayed is within the affected ranges: >= 1.1.17 and < 1.4.2, OR >= 1.5.0 and < 1.5.13
-
Verify version matches 1.4.1 exactlyConfirm if the installed version is exactly 1.4.1, which is explicitly listed as affectedAffected if Version is exactly 1.4.1
-
Confirm Cube API is network accessibleCheck network configuration or firewall rules to determine if Cube API endpoints are exposed to network requestersAffected if Cube API is externally accessible and version is within affected ranges
You are affected if your Cube.js version is 1.1.17 through 1.4.1, 1.4.2 through 1.5.12, or specifically 1.4.1, and the API is network accessible.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped1.4.21.5.13
Upgrade Cube to version 1.5.13 or 1.4.2 (or later) to apply the security patch.
1.4.2 (for 1.4.x branch) or 1.5.13 (for 1.5.x branch)
- Identify your current Cube.js version by checking package.json or running `npm list cubejs`
- If you are on the 1.4.x branch, upgrade to version 1.4.2 or later: `npm install cubejs@^1.4.2`
- If you are on the 1.5.x branch, upgrade to version 1.5.13 or later: `npm install cubejs@^1.5.13`
- After upgrading, restart your Cube.js server
- Verify the API is accessible and functioning normally with test queries
